The Weather Annihilator is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a weather-controlling devise created by Dr. Ivo Robotnik to take over Mobius.
The Weather Annihilator was built by Robotnik to freeze the nearby area of Mobius. This would allow him to track any living creature by using heat scanners. After a week of use, and no signs of the Knothole Freedom Fighters, Robotnik deemed it a success. He was quickly proven wrong when the Freedom Fighters attacked the Annihilator right when Robotnik was going to turn it off. Despite the efforts of Snively to stop the Freedom Fighters, Sonic destroyed the Weather Annihilator with the help of the Arctic Freedom Fighters.
